(Recovered, supplied) ADAU1788BCBZRL (ADI) Dual ADC Single DAC low power codec with audio DSP.

Product Description:

The ADAU1788 is a codec with two inputs and one output that integrates two digital signal processors (DSPS). The path from the analog input to the DSP core to the analog output has been optimized for low latency and is suitable for noise cancellation headsets. By adding a small number of passive components, the ADAU1788 provides a noise-cancelling headset solution.

Features:

Programmable FastDSP audio processor

Up to 768 kHz sampling rate

Biorder filter, limiter, volume control, mixing

28 bit SigmaDSP audio processing kernel

Visual programming is possible using SigmaStudio

Up to 50 MIPS performance

Low latency 24-bit ADCs and Dacs

96 dB SNR (signal through PGA and ADC with A-weighted filter)

105 dB integrated SNR (signal through DAC and headset with A-weighted filter)

Serial port fSYNC frequency range is 8 kHz to 768 kHz

Group delay from analog input to analog output is 5 μs (fS = 768 kHz)

2 single-ended analog inputs that can be configured as microphone or line inputs

4 digital microphone inputs

1 analog differential audio output that can be configured as a line output or microphone driver

Supports PLL with any input clock frequency from 30 kHz to 27 MHz

Full duplex, 4 channel ASRCs

16-channel serial audio port with support for I2S, left-justified or up to TDM16

8 interpolators and 8 extractors, with flexible routing

Power source
